built in operators java code example

Example 1: Operators in java

// java unary increment (++) operator
public class JavaUnaryOperator
{
   public static void main(String[] args)
   {
      int a = 23;
      // 23 gets printed and increment to 24
      System.out.println("Java post-increment = " + a++);
      // a value was 24, incremented to 25
      System.out.println("Java pre-increment = " + ++a);
   }
}

Example 2: Operators in java

// java unary (~) operator
public class JavaUnaryOperator
{
   public static void main(String[] args)
   {
      int a = 8, b = -4;
      System.out.println("a = " + a);
      System.out.println("b = " + b);
      System.out.println(a + " java bitwise complement is = " + ~a);
      System.out.println(b + " java bitwise complement ia = " + ~b);
   }
